室温螺旋有序六角铁氧体的逆磁电实验

Converse Magnetoelectric Experiments on a Room Temperature Spirally Ordered Hexaferrite

Khabat Ebnabbasi, Carmine Vittoria, Allan Widom

摘要:

对室温下有序六角铁氧体Sr_3Co_2Fe_24O_(41)的磁电性能进行了测量。测量的性质包括磁导率、磁化强度和应变,所有这些都是电场E和磁场强度H的函数。材料六角铁氧体Sr3Co2Fe24O41表现出时间反转和宇称的对称性破缺。这两种对称性的乘积保持不变。这是这些磁电材料的中心特征。提出了一个简单的物理模型来解释这些材料中的磁电效应。

英文摘要:

Experiments have been performed to measure magnetoelectric properties of room temperature spirally ordered Sr3Co2Fe24O41 hexaferrite slabs. The measured properties include the magnetic permeability, the magnetization and the strain all as a function of the electric field E and the magnetic intensity H. The material hexaferrite Sr3Co2Fe24O41 exhibits broken symmetries for both time reversal and parity. The product of the two symmetries remains unbroken. This is the central feature of these magnetoelectric materials. A simple physical model is proposed to explain the magnetoelectric effect in these materials.
